Good thoughts all. I appreciate the input. I find I don’t noodle through this sort of issue like I used to! This used coach is new to me over the winter so I’m still exploring. I don’t think there is a valve between the FWT and the pump other than the winterizing selection valve. It would be a likely source of the problem if there is. One thing I didn’t try is feeding the coach from my freestanding bottle through the winterizing valve. I’ll do that this weekend and if it operates properly it will pretty much leave me with the waterline from the FWT sucking air. BTW, my freshwater tank was full to the brim. It’s interesting to me that the pump was replaced by the previous owner even though the coach is barely three years old. Wouldn’t surprise me a bit if this is the reason! But I’ll figure it out. It’s not “rocket surgery”
